Iscar 5550222 Turning Insert CCMT32WG IC8250 Carbide

Product Description

The ISCAR 5550222 is a solid carbide turning insert in the CCMT32WG geometry, part of the Isoturn series. It carries a multilayer PVD coating of TiCN, Al2O3, and TiN under the IC8250 manufacturer grade, engineered for wear resistance and thermal stability during interrupted and continuous cuts. The insert features an 80-degree diamond shape with a positive rake angle and a wiper edge for improved surface finish. With a 3/8-inch inscribed circle and a 0.0313-inch corner radius, it is sized for medium finishing and semi-finishing operations. Licensed machinists and CNC lathe operators install this insert as part of a screw-held toolholder system.

This insert is designed for turning stainless steel and carbon steel workpieces in ISO material groups M and P. The WG chip breaker geometry promotes controlled chip flow on these materials, making it well suited for external turning on CNC lathes in production and job-shop environments. The CCMT insert style fits standard screw-clamp toolholders accepting CCMT32 inserts. Maximum depth of cut is 2.50 mm (0.0984 inches), positioning this insert for finishing and light semi-finishing passes rather than heavy stock removal.

Key Features

• IC8250 grade with multilayer PVD TiCN, Al2O3, and TiN coating for extended tool life on stainless and steel
• Wiper edge geometry for improved surface finish at standard feed rates
• Positive rake angle reduces cutting forces and heat generation
• 80-degree diamond insert shape (CCMT style) provides two cutting edges per insert
• WG chip breaker optimized for stainless steel and steel ISO groups M and P
• Compliant with ISO 13399 tooling data standards for CAM and tooling system integration

Compatibility

Designed for use in standard screw-clamp toolholders accepting CCMT32-style inserts with a 7-degree relief angle (clearance code C, tolerance code M). Compatible with ISO material groups M (stainless steel) and P (carbon and alloy steel) per ISO 13399.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key specified by the toolholder manufacturer to secure the clamping screw — do not overtighten. Inspect the toolholder pocket and seating surfaces for chips or debris before seating the new insert to ensure proper contact and runout.
